$\textbf{\underline{\underline{Explanation :-}}}$

$\textsf{\underline{\underline{Given : }}}$

560 icecreams cost Rs. 3920

$\textsf{\underline{\underline{To find : }}}$

The cost of 6 dozen icecreams

$\textsf{\underline{\underline{Solution :}}}$

$\implies$ 72 icecreams

We can find the cost of 72 icecreams by Proportion :

Consider the cost of 72 icecreams as x

560 : 3920 : : 72 : x

$\boxed{\sf{Mean \times Mean\:Terms = Extreme \times Extreme \:Terms}}$

Mean terms = 3920 and 72

Extreme Terms = 560 and x

$\tt{\implies} \: 3920 \times 72 = 560 \times x \\\tt{\implies} \:282240 = 560x \\ \tt{\implies} \:x = \frac{282240}{560} \\ \tt{\implies} \:x = 504$

x = 504

$\therefore$ The cost of 6 dozen icecreams is Rs.504.

$\textbf{\underline{\underline{Verification :-}}}$

$\tt{\implies} \: 3920 \times 72 = 560 \times504 \\\tt{\implies} \:282240 = 282240$
